can anyone give me a hint? I woke up to the red light under first HDD. The HDD is cca one month old after old one has reported failure (come to think of it, I did not checked it too much, seen the red light, bought new one). After month of usage, the new one reports as bad in dasboard. I found it weird, so I pulled the smart data from smartctl, run quick test (passed), waiting to complete long test.
Thing is, I cannot find anything wrong in the smart data in the “failing” drive. Anyone can spot something?

Had « SMART » failure reported for the first drive. Then bought a WD RED Pro to replace it.
The new new drive was reported as being in « bad » state and has consequently been already RMAed.
And now the replacement disk is also said to be in bad state, each time with red light on drive 1.
I am in touch with support since.
I am running tests as required. System test and quick test has been said to be OK. Complete test is undergoing…
Full test done, no errors. Raised a ticket too, added smart data + logs. Let’s see what they come back with. Seems that I bought a new drive for no reason whatsoever.
On my side too.
All tests (system, quick, full) passed successfully.
Waiting for t’support to update me on this.
But that raises the question of who is to be trusted, why would my My Cloud EX2 Ultra reports that the disk is in bad state… twice in this case.
I’ve had the same red LED on the first drive, a couple times (PR4100).
I found that rebooting the PR4100 clears the red LED. To me, this likely indicates a software problem rather than a hardware failure.
Additionally, on one occasion, I copied all the S.M.A.R.T. data (red LED indicated), then rebooted, and again copied the S.M.A.R.T. data (blue LED indicated), and compared the two. No differences.
I am having similar issues with drive bay 3 in my PR4100.
Are you removing the drive in placing it within a separate drive dock to obtain the SMART data? It seems that my PR4100 reads valid data for a while but, after 10 minutes the red light is lit on bay 3.
Very weird.
This is a second PR4100 that I have had. I have sent a different one back because drive bay 4 kept failing.

The other two drives look normal.
By the way, I have went through this before on this NAS. I used Active @KillDisk utility to erase the drives and rotate the four drives that I have but, the issue returned.
I will reach out to WD support tomorrow to see what they can suggest.
I am only using 3 drives right now as the 4th would have been the spare.

Oh, the first 3 drives have the same drive type installed WD Red Plus 6TB drives. If I reboot the drive shows up for a while - SMART data is assessable from the web dashboard but, eventually, it flags the drive as bad.
The S.M.A.R.T. data displayed by the dashboard is a crock of BS because it intentionally omits the RAW_VALUE attribute. Otherwise, without including results from the problematic drive, what’s the point?
After I reboot the NAS, there is a few minutes before it times out where SSH allows me to obtain the SMART data. Here is what I have for Drive 3.

The drive looks ok, except for a number of UDMA_CRC_Error_Count errors, which generally indicates an issue with the SATA connection, but the errors could also be caused by the drive itself.
My guess would be that there’s an issue with the SATA backplane within the NAS itself, and swapping out the drive would likely have zero effect.
Personally, I doubt that the problem is gone for good. SATA problems are often caused by dirty connectors, either on the backplane, the drive, or both. Perhaps a few well placed shots of canned air might do the trick?
It could also be a hardware problem, but without extensive testing, and perhaps a bit of trial and error, there’s no way to know for sure.
